What are two glassware items?
The Types of Glassware
- Bulb and graduated pipettes. These are used to transport specific amounts of fluids from one place to another.
- Burettes. These are used to dispense exact quantities of liquid into another vessel.
- Beakers.
- Volumetric flasks.
- Condensers.
- Retorts.
- Funnels.
- Petri dishes.
How can you look at a piece of glassware and tell if it will give a precise measurement?
When water is placed in a glass or plastic container the surface takes on a curved shape. This curve is known as a meniscus. Volumetric glassware is calibrated such that reading the bottom of the meniscus, when it is viewed at eye level, will give accurate results.
What are the glassware items?
Drinkware, beverageware (in other words, cups) is a general term for a vessel intended to contain beverages or liquid foods for drinking or consumption.
- Beaker.
- Beer glassware.
- Coffee cup.
- Cup.
- Jar.
- Mug.
- Paper cup.
- Pythagorean cup.
What is the most precise glassware?
volumetric flask
The volumetric flask is the most accurate, but it only measures 1 volume—in this case, 100mL. If you need to measure other volumes besides those on volumetric flasks, then the graduated cylinder is the best tool.
What is glassware used for?
Examples of glassware used for measurements include: Graduated cylinders are cylindrical containers used for volumetric measurements. Volumetric flasks are for measuring a specific volume of fluid. Burettes are used to disperse precise amounts of liquid reagents.
What glassware is most accurate?
Volumetric pipets, flasks and burets are the most accurate; the glassware makers calibrate these to a high level of accuracy. The accuracy is usually measured in terms of the tolerance, which is the uncertainty in a measurement made with the glassware.
What glassware is least accurate?
Graduated cylinders, beakers and Erlenmeyer flasks have less accuracy than volumetric glassware. Graduated cylinders can generally be considered reliable to within 1 percent.
What glassware needs calibration?
Type B. Double the tolerance limit of class A glassware. It is used for routine work and requires calibration before putting to use.
